IMPROVEMENT lN SASH-BALANCES.

Specification forming part of Letters Patent No. 130,476, dated August 13, 1872.

Specification describing certain Improvements in Window-Sash Supporters, invented by ANDREW J. CHASE, of Boston, in the county of Suffolk and State of Massachusetts.

The object of this invention is to provide a cheap,'sa-fe, and convenient means for supporting Window-sashes-and admit of their being easily and quickly disconnected from such supporting mechanism, and removed from their frame or casing for the purpose of cleaning, or whenever desired; and it consists in the use of the ordinary flat metallic strap passing over a friction-pulley connected to a balance-Weight, and having its opposite end provided with a clasp,which engages with a similar catch upon the sash-frame near its lower end, the said clasp bein g provided with a ring which projects below the bottom of the sash when raised, and may be clasped with the iingers and inserted under a pivoted hook let into the frame, thus supporting the weight, when the sash may be raised, disconnecting the clasp and catch 5 the stop-bead being removed, the sash may be removed, leaving the weights suspended by the straps, as above described. When the sash is replaced and let drop down, the clasps and catches engage as before, and the sash is balanced by the weights as the rings disengage from the hooks, which fall down and recede from the path of the rings as the sash is raised or lowered-the clasp, catch, ring, and hook being automatic to connect the strap and weight to the sash, and disconnect the same from the hook upon the frame.

Figure l is a perspective view of the end of the strap and clasp with ring. Fig. 2 is a similar view ofthe catch as attached to a portion of the sash. Fig. 3 is a section view through the sash, casing, strap, weight,and fastenings as connected when in use. Fig. 4 is a view of the hook with ring connected.

. A is the sash. B is the iiat metallic strap to which is attached the clasp C, and toits opposite end the weight D. e is a frictionpulley attached Vto the casing F in the usual manner. G is the catch. H is the hook, and J is the ring. These may be struck up out of brass or made of any cast metal desired. The metal strap may be of brass, steel, or iron, and sufficiently thin to admit its passing freely over the pulleys when the sash and weights are attached.

What I claim is- 1. The automatic coupler, composed of clasp O, catch G, hook H, and rin gv J, or their equivalents, in combination with sash A,vveight D, and casing F, substantially as and for the purpose set forth.

2. The combination of the flat metallic strap B and weight D with clasp O, catch G, sash A, and ring J ,when constructed and. arranged to operate substantially in the vmanner described, as and for the purpose set forth.
